Research fields


The main research fields of JDL include: audio-video coding/decodingˇˇtechnologies, content-based information retrieval from mass multimedia data, Biometrics, intelligent human-computer interaction, and applied algorithms. Currently, several projects from the National "973" Programme, the National Fund of Sciences, the National Hi-Tech R&D Programme (863), the Key Technologies R&D Programme, and the Knowledge Innovation Program of Chinese Academy of Sciences, are being studied in the lab. JDL have not only accumulated solid research foundation in self-field, but also enhance the subject crossing to extend to the assistance research in being science.

Proteomics Research Based on Information Technology (Project List) ˇˇˇˇ
The project is a knowledge innovation project of Chinese Academic Science, a Proteomics research on fatal diseases of human is one of the biggest national demands. The research on theoretical models and algorithms of bioinformatic techniques for the problems of protein identification, 3D protein structure analysis and function prediction in current proteomics is of great theoretical significance and practical importance. This national "973" program project aims at investigating various mathematic models and algorithms to establish bioinformatic technology platform for proteomics research, employing novel computational methods and techniques to develop high-throughput and accurate protein identification and protein 3D structure analysis software system, assisting biologists to identify new proteins and analyze their structures and functions, and establishing protein databank system. The goal of the project is to develop new methods for high-throughput and accurate protein identification via mass spectrometry and create relative software system on the internationally advanced level. Novel algorithms for protein 3D structure recognition and analysis will be proposed along with relative software system. A protein databank system with the combined functions of data management, search and visualization will also be established.
